Max Verstappen has highlighted a "temperamental" problem that could impact the Dutch Grand Prix.
The two-time World Champion heads into the weekend having won the last eight races in a row, with him set to equal Sebastian Vettel's Red Bull record of nine in a row from the 2013 season.
The race has already been threatened by a protest among local taxi drivers, who could be blocked from accessing the circuit over the weekend without a proper permit.
But he warned that weather could play a factor in the weekend, as it has done in the last five Formula 1 races.
